IMPRovgMENT IN TABLE-LEAF SUPPORTS.

4General Description.

' In tbe drawing- Figure 1 is a sectional elevation of our improvement as applied to a table. v

Figure 2 a bottom view of the same, the parts being represented 'as locked together.

Figure 3, a similar View with-the bolt-head with- Figure 4, a view in cross-section, showing "the arrangement and construction of the 4spring andl bolthead.

A represents a table-top having a leaf, B, hinged to itin the ordinary manner.

C is'the brace or long arm of the lever-support, at-v tached to the nuclei' side ofthe table, and' held loosely at one end bythe lloop c, and at the other end it is provided with a semicircular bolt-head, c, acting as the `short arm of the lever.

This bolt-head inter-matches with a socket-piece, D,

secured to the under side of the table-top, and having two lugs or bearings, djd', which receive and sustain the pressure of the leat' through the long arm Aof lever O, [l acting as the fulcrum, and d fn'nishing a sion, g, of the socket-piece D- to retain vit in position,

,as shown in lig. et.

A small cord or wire, J, is attached to the eye ,h of the bolt-head, and .extends thencerto; a convenient point at the outer edge of the table, by which means'- the bolt-head may be readily withdrawn to allow the leaf to descend.

v The operation of the invention is as follows:

When it is desired to lower theleaf the bolt-head c of the brace C is disengaged from the socket, again st the resistance of the ,spring G, as shown in tig. 3, by

Y means of the wire or cord lJ All restraint on the leaf being thus removed, it is at liberty to descend.

In again raising .the leaf' the socket-piece is-presented to the bolt-head at thev proper angle, wl1 en the latter is again drawn into the former by the spring, and the-lock of the parts, as' before described. is complete.

requires -no 'reaching beneath the tablet-o1 adjust it; its action of locking when the leaf is raised is automatic; and in lowering the leaf the cord or wire atv theouter edge of the table has only to be slightly pulled to withdraw the bolt-head from its lock-in the socket. l

The compression vof the spring,rather than its distension is to be noted, this beingr the only part liable :to deteriorate in use.

It can be manufactured at small cost, and being .made of metal, is very durable. The parts being simple andniade of metal, are not liable to shrink," swell,

".or otherwise'get out of order.

The ease with which it may be attached to all ordinary tables is also a feature of importance, it being only necessary' to .insert three'screws in the socketpiece, theloop at the outer end of the brace, and another small loop or eye to support the detaching-cord or wire at the edge ofthe table.

What we claim as our invention, and desire to se. cure by Letters Patent, is',-

1.4 Thecombinatiou of the lever-arm or brace C with the semicircularbolt-head c, which iuterlocks with the socket-piece D, for .the purpose described.

2. The socket-piece D, for receiving the bolt-head c of brace C, andv having lugs or bearings d d', in com-v bination with the spring G, as described.

In witness whereof we have hereunto signed our names in the presence'oi two subscribing witnesses.`
